Air pressure stabilizing device for bottle blowing machine

The utility model discloses an air pressure stabilizing device for a bottle blowing machine, which comprises an operating table, a stable blowing mechanism is mounted at the upper end of the operating table, and bottle blowing cooling devices are mounted at the left end and the right end of the operating table. According to the utility model, the stable blowing mechanism is installed, the pre-blowing main valve of the bottle blowing machine is replaced by the pre-blowing proportional main valve, and the old pre-blowing valve is replaced by the new pre-blowing valve, so that the fluctuation of a bottle blowing process during production is reduced, and the pressure detection meter is arranged on the pre-blowing proportional main valve; the pressure of gas blown out by the gas blowing pump mechanism can be displayed on the pressure detection meter, the pressure detection meter is connected with the PLC, if the blown-out pressure is too large, the PLC can control the electromagnetic valve, so that the gas pressur
